schema.org
An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org [style guide](https://schema.org/docs/styleguide.html).

See [background notes](https://schema.org/docs/datamodel.html#identifierBg) for more details.

A short string listing or describing pronouns for a person. Typically the person concerned is the best authority as pronouns are a critical part of personal identity and expression. Publishers and consumers of this information are reminded to treat this data responsibly, take country-specific laws related to gender expression into account, and be wary of out-of-date data and drawing unwarranted inferences about the person being described. In English, formulations such as "they/them", "she/her", and "he/him" are commonly used online and can also be used here. We do not intend to enumerate all possible micro-syntaxes in all languages. More structured and well-defined external values for pronouns can be referenced using the [StructuredValue](https://schema.org/StructuredValue) or [DefinedTerm](https://schema.org/DefinedTerm) values.
The publishingPrinciples property indicates (typically via [URL](https://schema.org/URL)) a document describing the editorial principles of an [Organization](https://schema.org/Organization) (or individual, e.g. a [Person](https://schema.org/Person) writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a [CreativeWork](https://schema.org/CreativeWork) (e.g. [NewsArticle](https://schema.org/NewsArticle)) the principles are those of the party primarily responsible for the creation of the [CreativeWork](https://schema.org/CreativeWork). While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a [funder](https://schema.org/funder)) can be expressed using schema.org terminology.
